Site(s) Implementation Monitoring Monitoring and Reporting Monitoring Verification of Mitigation Measures Affected Procedures Responsibility Action Schedule Compliance passerine birds not more than 14 days prior to any ground-disturbing activity or vegetation removal.Surveys will include all line-of-sight trees within 500 feet(for raptors)and all vegetation within 250 feet for all other species. • Based on the results of the surveys,avoidance procedures will be adopted, if necessary,on a case-by-case basis.These may include construction buffer areas(up to several hundred feet in the case of raptors)or seasonal avoidance. • Bird nests initiated during construction are presumed to be unaffected by project activities,and no buffer would be necessary except to avoid direct destruction of a nest or mortality of nestlings. • If pre-construction surveys indicate that nests are inactive or potential habitat is unoccupied during the construction period, no further mitigation is required if work is initiated within 14 days of the survey. Trees and shrubs that have been determined to be unoccupied by nesting or other special-status birds may be pruned or removed within 14 days of the pre-construction survey.Should activities be delayed beyond 14 days,pre-construction surveys shall be repeated prior to the start of work. i 4.E-1.Biological Resources(cont.)

A 100-foot no disturbance buffer is a typical protective buffer distance; however,buffer width may be modified by the qualified biologist depending on existing screening around the roost site(such as dense vegetation or a building)as well as the type of construction activity which would occur around the roost site.
